概括
在切除前的左心房张力和左心房附属体排空速度预测了切除后心房的复发. 这些指标可以改善患者选择除手术.
科学领域:
- 心脏病学
- 电生理学
- 医学成像
背景情况:
- 前庭动是一种常见的心律失常,对健康有重大影响.
- 在AF切除后的复发率仍然很高,突显了需要更好的患者分层.
- 预测工具对于优化治疗策略和患者选择至关重要.
研究的目的:
- 评估左心房应变 (LAS) 和左心房附属体排空速度 (LAAeV) 作为切除后AF复发的预测因素.
- 确定LAS和LAAeV的结合是否可以提高AF复发的预测准确性.
- 评估这些指标的潜力,以改善患者选择的AF切除手术.
主要方法:
- 这是一项前性队列研究,对32名经过冷或射频切除的患儿进行了治疗.
- 通过胸腔回声扫描测量前摘除LAS和通过食道回声扫描测量LAAeV.
- 患者被随访了1年,在3个月的空白期后,复发被定义为AF发作> 30秒.
主要成果:
- 在21. 9%的患者中观察到AF复发.
- 脱离前的LAS (全球≥33. 56%) 和LAAeV (≥42. 7cm/ s) 是没有复发的显著预测指标 (AUC分别为81. 4%和94%).
- 结合LAS和LAAeV,预测复发的灵敏度达到了100%和特异性达到了94%.
结论:
- 切除前的LAS和LAAeV是切除后的AF复发的强有力的预测因素.
- 将这些心声学参数整合到手术前的评估中可以优化患者的选择.
- 需要进一步的研究来验证特定年龄的切断值和长期结果.

Assessment of apical radial pulse
Apical-Radial (A-R) Pulse Assessment
The A-R pulse assessment involves simultaneous evaluation of the apical and radial pulses. When the apical and radial pulse rates vary, this assessment helps identify a pulse deficit.

Assessment of the Abdomen II: Percussion
Percussion is a fundamental technique used to assess the liver, spleen, and abdominal organs by tapping the abdomen and interpreting the resulting sounds. This method helps identify fluid, distention, and masses through variations in sound, such as the high-pitched tympany of air-filled areas and the dullness of solid masses. Understanding how to percuss these organs provides valuable information for healthcare professionals in diagnosing conditions early.
